You are what You grow
From here
Drewnowski gave himself a hypothetical dollar to spend, using it to purchase as many calories as he possibly could. He discovered that he could buy the most calories per dollar in the middle aisles of the supermarket, among the towering canyons of processed food and soft drink. (In the typical American supermarket, the fresh foods — dairy, meat, fish and produce — line the perimeter walls, while the imperishable packaged goods dominate the center.) Drewnowski found that a dollar could buy 1,200 calories of cookies or potato chips but only 250 calories of carrots. Looking for something to wash down those chips, he discovered that his dollar bought 875 calories of soda but only 170 calories of orange juice.
As a rule, processed foods are more “energy dense” than fresh foods: they contain less water and fiber but more added fat and sugar, which makes them both less filling and more fattening. These particular calories also happen to be the least healthful ones in the marketplace, which is why we call the foods that contain them “junk.” Drewnowski concluded that the rules of the food game in America are organized in such a way that if you are eating on a budget, the most rational economic strategy is to eat badly — and get fat.
This perverse state of affairs is not, as you might think, the inevitable result of the free market. Compared with a bunch of carrots, a package of Twinkies, to take one iconic processed foodlike substance as an example, is a highly complicated, high-tech piece of manufacture, involving no fewer than 39 ingredients, many themselves elaborately manufactured, as well as the packaging and a hefty marketing budget. So how can the supermarket possibly sell a pair of these synthetic cream-filled pseudocakes for less than a bunch of roots?
Guardian says peak oil has hit
from here
"The world soon will not be able to produce all the oil it needs as demand is rising while supply is falling. This is a huge problem for the world economy," said Hans-Josef Fell, EWG's founder and the German MP behind the country's successful support system for renewable energy.
The report's author, Joerg Schindler, said its most alarming finding was the steep decline in oil production after its peak, which he says is now behind us.
The results are in contrast to projections from the International Energy Agency, which says there is little reason to worry about oil supplies at the moment.
However, the EWG study relies more on actual oil production data which, it says, are more reliable than estimates of reserves still in the ground. The group says official industry estimates put global reserves at about 1.255 gigabarrels - equivalent to 42 years' supply at current consumption rates. But it thinks the figure is only about two thirds of that.
Global oil production is currently about 81m barrels a day - EWG expects that to fall to 39m by 2030. It also predicts significant falls in gas, coal and uranium production as those energy sources are used up.
Britain's oil production peaked in 1999 and has already dropped by half to about 1.6 million barrels a day.
The report presents a bleak view of the future unless a radically different approach is adopted. It quotes the British energy economist David Fleming as saying: "Anticipated supply shortages could lead easily to disturbing scenes of mass unrest as witnessed in Burma this month. For government, industry and the wider public, just muddling through is not an option any more as this situation could spin out of control and turn into a complete meltdown of society."
Mr Schindler comes to a similar conclusion. "The world is at the beginning of a structural change of its economic system. This change will be triggered by declining fossil fuel supplies and will influence almost all aspects of our daily life."
Jeremy Leggett, one of Britain's leading environmentalists and the author of Half Gone, a book about "peak oil" - defined as the moment when maximum production is reached, said that both the UK government and the energy industry were in "institutionalised denial" and that action should have been taken sooner.
"When I was an adviser to government, I proposed that we set up a taskforce to look at how fast the UK could mobilise alternative energy technologies in extremis, come the peak," he said. "Other industry advisers supported that. But the government prefers to sleep on without even doing a contingency study. For those of us who know that premature peak oil is a clear and present danger, it is impossible to understand such complacency."
Mr Fell said that the world had to move quickly towards the massive deployment of renewable energy and to a dramatic increase in energy efficiency, both as a way to combat climate change and to ensure that the lights stayed on. "If we did all this we may not have an energy crisis."
He accused the British government of hypocrisy. "Tony Blair and Gordon Brown have talked a lot about climate change but have not brought in proper policies to drive up the use of renewables," he said. "This is why they are left talking about nuclear and carbon capture and storage. "
